To all 20/111111 7 1 III (11fIBOJM'ZC/ib.

Be it known that I, Sinu'm, KATZ, a citizen of the United States, residing at'Ncw York, in the county of New York and State oi New York, have invented certain new and useful mprovenicnts in which the followingis a specification, such as will enable those skilled in the art to which it a-ppertains to make and use the same. 7 This invention relates to gas illunlinatiugfburners; and the object thereof is to providev a burner of't'his class which is so constructed. thatif the gas-should at any time he extinguished without cutting oil the llow thereof to thchurnpr the sa id flow of gas to'the burner will be autoinatically cut oil; and other objects in. view the sists ina buriier ol' the via bed andclaimed} fully disclosed in the l'ol on, of which the accompaform a part, in 'which the separate parts of my inmroviunent are designated by suitable referei'ice characters in each of the views, and in Which--- The invention i lowing spec ficeti nymg drawings -\F1guro 1 is a central vertical section of a or es-burner made according ig. 2, a transverse section on the line 2 2 of Safety Gas-Burners, of

and with this lured to inventmn "co tl ss spccihed con; wardly-dn'ec to my invention; pie (Z.

5 Fig. 1, and Fig. 3 a transverse section on the.

ing tubular extension I prefereb line 3 3 of Fig. 1.

In the drawings forming part of this specification I have shown an ordinary {gas-supydy pipe (1, provided witha valve o and a burnerattaohment member o and in. the practice oi" my invention 1 provide a burner comprising a tut- 1 I), provided at its lower end with a reducml. coupling member if and the upper end of which closed and provided with ports or passages It, which are arranged (.n mcentricnl around the central axis of the tube 5 in ti form of construction shown, a

' Mounted on the tube 6 is a verticallyauovable sleeve member 0, the lower end of which osed pplrsrecciv- 0 adapted to l'mtoiio burner-nipple (Z, and in practice form in tl end of the tube 1) and in ii the top of the sleeve the opening formed a. an annular is 0 on and the upper end of which is cl an provided centrally with av in an ordinary .3

member I; and around by the tubular extension groove 0, m which is laccd a packing-ring of any suitable nuitin'ial, preterablyfibrous materiel saturated with paraliin or other preservative liquid. Secured to the tube 1) below the sleeve meu'ibcr c is collar ly raised hy l l l i l l i re top surface oi the i i i edirected member 71- arm of a oke-shaped theri arm of which extends d posite side of the tube 7) to a predetermined point and is provided with an outwardly-directed finger g That side of thev collar or band f opposite the point where one of the arms of the yoke-shaped thermostat g sccurcd thereto is provided with an upwardly directed member f having a vorhcalhy-arranged slot or opening above which said nmmberj" is provided with an outwardly-direeted project ionf", ouwhi -h the linger mein ber g of the thermostat g rests, and said linger memlporig passes through a' keeper f sehe projection]. The lower end of lo sleeve member c is provided with an outtcd arm h, having an upwardly provided with an inwardly-- iirocted hook m mber h in connection-w-rith which the lilljj l g of the thorium start 9 operates, and the arm 71, is provided with a (l0YVIl\Vd.-r(li:) dil'tlCi/(Kl rod 2', which forms a handle for numipulntiug the sleeve member c in the process oi lighting the burner igniting the gas that escapes from the niplhc tube 7) is also provided in the form of constructing shown with a perforated partition which operates to regulate, to an extent, the flow of the f'itS through the burner; but said tube may 0 provided With any desired kind or class of a regulator.

The operation of this device will be readily understood from the foregoing description when taken in connocti n with the ecco1npanying drawings and the following statement .therooif Whenever it is desired to light the burner, the valve uostat g, the other means oi. the rod 'i, and the gas is allowed to flow through the burner and through the burner-tip d and is ignited in the usual manner. Tho flame of the gas striking the top portion of the thermostat g immediately expands the same, and ti'iisexpsnsion throwsout the finger g beneath the hook meu'iher 71 which is raised, as before de scribed, in the operation of igniting the gas, and when this is done the rod 'i may i I reie bottom surface of i leased, and as long the burner'is ignited. or

in operation the linger-f, operating in conncctiou with the hook member it will hold the sleeve oin its raised position. If at any time the gas should be extinguished Without cutting oil the low thereof, the thermostat 9 will immediately contract and the finger will be withdrawn from beneath the hook or hand f, to one side of which is secured one ownwarrlly on the op- 2 is opened, the sleeve 0 is member h and the sleeve will drop into the position shown in full lines in Fig. 1, and the flow of gas to the burner-tip Will-be cut off.

In practice the thermostat g is preferably made of different metals possessing difierent degrees of expansibilit under heat in order that the operation thereof will be -more quickly affected by the heat of the burner; but my invention is not limited to the material employed in the construction of the thermostat.

It will also be understood that when the sleeve 10 is in its lowest position, as shown 1n full lines in Fig. '1, the gas can'not escape from the tube 1), as the'top of'the sleeve 0 rests directly on the to of said tube, and these parts may be so ma e as to prevent the escape of gas, and the acking-ring e also serves to aid in accomplis in this result.

Having fully escribed my invention, what I claim as new, and desire to secure by Letters.Patent, is'

' i I. Agasburn'erof the class described, comprising'atube adapted atjits lower end to be connected'with a gas-supply ipe, said tube being'closed atits upper e'n and provided with"conceiitrically-arran'ged ports or passages, 'asle'eve mounted on said tube and closed at its upper end and rovided centrally with a burner-ti a col arsecured to said tube below said s eeve, a yoke-'sha ed thermostat one arm of which is secure to said collar and the other arm of which is-pro vided'wit'h'an outwardly-directed fin 'er, and aniarm'connectedwith the lower end of said sleevealid provided'with an inwardl -directedlhook' 'member in connection wit which sai and descri ed. v p
